Drug class

Polystyrene sulfonates are a group of medications used to treat high blood potassium.[1] Effects generally take hours to days.[1] They are also used to remove potassium, calcium, and sodium from solutions in technical applications.

Common side effects include loss of appetite, gastrointestinal upset, constipation, and low blood calcium.[1] These polymers are derived from polystyrene by the addition of sulfonate functional groups.

Sodium polystyrene sulfonate was approved for medical use in the United States in 1958.[1]

A polystyrene sulfonate was developed in the 2000s to treat Clostridium difficile associated diarrhea under the name Tolevamer,[2] but it was never marketed.
